Thanks for your reply. In version 2 of the Technical Product specification of the DB75EN desktop board, it was mentioned that the maximum supported resolution of the DVI-D interface was 2048x1536@75 Hz (QXGA). Hence, I had used a dual link DVI-D cable to connect the computer to the monitor. After reading your reply, I found that the Technical Product specification document has been updated to version 5 wherein it has been mentioned that the DVI-D interface can support resolution upto 1920x1200@60 Hz. So I agree with you that I need to use a single link DVI-D cable instead of the dual link DVI-D cable. But now I have two follow up questions.
1. The DVI-D socket on both my motherboard and my monitor can accommodate all 24 pins of a DVI-D dual link male connector. So why is this kind of a design there when the graphics controller supports single link DVI-D?
2. If I uninstall Intel's graphics drivers and allow the OS to use Microsoft's own drivers that are supplied with Windows 7, how is it that using the same dual link DVI-D cable, I am able to get the display to work properly?
Thanks a lot for your time.
Hi Sayantan Mitra,
Our graphics controllers do not support the DVI dual link and this is because of the driver and internal design of the controller. You can try using the windows generic drivers but we cannot guarantee the correct functionality. As per your post, it seems that it is working but our controller is design to use DVI Single link only.
